Docker fails to build on Ubuntu 22.04

[bryanhughes]

I have a fresh install of Ubuntu 22.04. When I try to do the docker build as in the instructions I get the following:

$ sudo docker build -t edgetpu .

Try removing json from that line in the docker file. It should be part of the standard library, so i’m not sure why it's in there. Your host OS shouldn’t make a difference though.

Thank you! Also, thank you for making your work available. I get docker to build and run, but then throws the following:

I am coming to realize what a piece of garbage this device is and Google's support of it. Sad because it has so much potential.

[jveitchmichaelis]

How are you running Docker? Can you see the device from inside the container? I'd guess this is a permission issue, but not sure.
